Windows 10 November Update mysteriously pulled, as concerns about bugs grow
Downloadable versions of Windows 10 version 1511, the November 2015 update, appear to have been removed after their release earlier this month.
Initially, Microsoft let people download full copies of the installer using the Media Creation Tool (MCT). Media produced with the MCT can be used to perform both upgrades and clean installations, and it's especially convenient when updating multiple systems, as it ensures that only a single download is required. But the version 1511 MCT has been removed, and replaced with the original July version. Systems can still be upgraded to the November update, but direct installation is no longer possible. Instead, the original RTM version must be installed, and the upgrade to 1511 performed through Windows Update.
This is both inconvenient and mysterious. The ability to install 1511 on clean systems is obviously quicker than going via the RTM version. It means one large download instead of two. Upgrading multiple systems with the MCT is also obviously preferable. It's mysterious because it's not really clear why the 1511 installer has been pulled.
